@gasket/plugin-nextjs

This plugin adds Next.js to your application.

Installation

New apps

Recommended

gasket create <app-name> --plugins @gasket/plugin-nextjs

Existing apps

npm i @gasket/plugin-nextjs next react react-dom

Modify plugins section of your gasket.config.js:

// gasket.config.js
module.exports = {
  plugins: {
    add: [
+      '@gasket/plugin-nextjs'
    ]
  }
}

Adding a Sitemap

When creating a new application with this plugin, you will be prompted with a question in the CLI asking if you would like to add a sitemap to your application.

Answering yes to this question will install next-sitemap as a dependency, generate a next-sitemap.config.js file, and add a sitemap npm script to your package.json. next-sitemap is an npm package that generates sitemaps and a robots.txt file for Next.js applications. Learn more by reading the next-sitemap docs.

Configuration

  • Instead of adding a dedicated next.config.js, the nextConfig property within gasket.config.js is used. Everything you can configure in the next.config can be added here.

It is also possible for apps to config Next.js using the gasket.config.js file. To do so, specify a nextConfig object property in the same form as what you would set for custom configurations or using Next.js plugins.

For general Webpack configurations, it is recommend to utilize features of the Gasket webpack plugin.

Example configuration

module.exports = {
  plugins: {
    add: ['@gasket/nextjs']
  },
  nextConfig: {
    poweredByHeader: false,
    useFileSystemPublicRoutes: false
  }
};

Example with plugins

const withSass = require('@zeit/next-sass');
const withCss = require('@zeit/next-css');

module.exports = {
  plugins: {
    add: ['nextjs']
  },
  nextConfig: withCss(
    withSass({
      /* config options here */
    })
  )
};

Internationalized Routing

When using this plugin along with @gasket/plugin-intl to determine and provide locale files, be sure to set the i18n config for defaultLocale and supported locales in the intl plugin config, instead of the nextConfig. This will be used by the Gasket Intl plugin, and also passed along with the Next config for i18n routing.

// gasket.config.js
module.exports = {
  intl: {
+    defaultLocale: 'en-US',
+    locales: ['en-US', 'fr', 'nl-NL']
  },
  nextConfig: {
    i18n: {
-    locales: ['en-US', 'fr', 'nl-NL'],
-    defaultLocale: 'en-US',
    domains: [
      {
        domain: 'example.com',
        defaultLocale: 'en-US',
      },
      {
        domain: 'example.nl',
        defaultLocale: 'nl-NL',
      },
      {
        domain: 'example.fr',
        defaultLocale: 'fr',
      },
    ],
    }
  }
}

Also note when using @gasket/plugin-intl to determine the locale, that the NEXT_LOCALE cookie will have no effect. You can, of course, hook the intlLocale lifecycle in an app to enable that behavior if desired.

Lifecycles

next

Executed when the next server has been created. It will receive a reference to the created next instance.

module.exports = {
  hooks: {
    /**
     * Modify the Next app instance
     * @param  {Gasket} gasket The Gasket API
     * @param  {Next} next Next app instance
     */
    next: function next(gasket, next) {
      next.setAssetPrefix('https://my.cdn.com/dir/');
    }
  }
};

nextConfig

Executed before the next server has been created. It will receive a reference to the next config. This will allow you to modify the next config before the next server is created.

module.exports = {
  hooks: {
    /**
     * Modify the Next config
     * @param  {Gasket} gasket The Gasket API
     * @param  {Object} config Next config
     * @returns {Object} config
     */
    nextConfig(gasket, config) {
      return {
        ...config,
        modification: 'newValue'
      };
    }
  }
};

nextExpress

Provides access to both next and express instances which allows next.render calls in express-based routes.

module.exports = {
  hooks: {
    nextExpress: function (gasket, { next, express }) {
      express.post('/contact-form', (req, res) => {
        // DO STUFF WITH RECEIVED DATA
        //
        // And once we're done, we can `next.render` to render the `pages/thanks`
        // file as a response.
        next.render(req, res, '/thanks', req.params);
      });
    }
  }
};

nextFastify

Provides access to both next and fastify instances which allows next.render calls in express-based routes.

module.exports = {
  hooks: {
    nextFastify: function (gasket, { next, fastify }) {
      fastify.post('/contact-form', (req, res) => {
        // DO STUFF WITH RECEIVED DATA
        //
        // And once we're done, we can `next.render` to render the `pages/thanks`
        // file as a response.
        next.render(req, res, '/thanks', req.params);
      });
    }
  }
};

nextPreHandling

Enables execution of custom logic just prior to an HTTP request being handed to next.js for processing. Hooks receive the request, response, and next server (not to be confused with the next function used by express-like middleware):

module.exports = {
    hooks: {
        async nextPreHandling(gasket, {
            req,
            res,
            nextServer
        }) {
            await doPreRenderingLogic(req, res);
        }
    }
}

Utilities

This plugin adds a middleware which attaches a getNextRoute function to the request object. It is intended for use in server contexts where you need to know how a request will route to a next.js page. This async function returns null if the manifest could not be parsed or if the requested URL does not match a route. If a match is found, an object with these properties is returned:

Property Type Description
page String The page name/path used to identify a page within next.js
regex RegExp The regular expression that matches URLs to the page
routeKeys Object For dynamic routes the mapping of URL placeholders to parsed route parameters
namedRegex RegExp Like regex, but named capturing groups are included to populate dynamic routing parameters
async function someMiddleware(req, res, next) {
  const route = await req.getNextRoute();
  if (route) {
    const { groups } = req.url.match(route.namedRegex);
    console.log(`Matched ${route.page} with parameters`, groups);
  }
  
  next();
}
